Congress: Ethics? What's that?

Yea, it seemed an awful basic question for you joe. And, of
course I fell for it. Agreed though that software RAID is like Congress creating
its own ethics rules--just a bad idea all around.

ROFL!
That was more of a case of purposely refusing to
acknowledge software RAID versus truly understanding what it is. I have had far
more than my share of times trying to rebuild software raid configs.

Software RAID is where the OS (in this case) handles the
striping of the data rather than the hardware (usually the
controller).

o Software RAID? What's that?
o Yeah I am not a fan of mirrors. I like lots of
spindles. But then I tend to work with big busy directories with
Exchange beating on it. Being 64 bit you don't have to worry _as much_
assuming you have enough RAM to cache your entire DIT but you still have to load
that baby in the first place so I would still recommend RAID 0+1, 10, or 5 or if
you don't care about fault tolerance the fastest is RAID-0.
o I would say if you are going 64 bit, make sure you make
it a priority to get enough RAM to hold your entire DIT. That is the cool
thing about getting 64 bit.

There would be a little more to gain than that but often that's the
reason. joe might point out that a two mirror configuration is not his
optimal configuration. I'm pretty sure he'd also point out that compared with
software raid, that he'd take that option. :)
I can honestly say I'd agree with him on this one. Software mirroring for
this type of application is never a good idea. The slower spindle speeds
likely won't be enough of an issue to matter in your configuration. Unless you
have a very large DIT <queue jokes here> or applications that pound the
snot out of the individual servers spindle speed won't be nearly as important.
Since it's 64 bit you're after, spend some money on the memory and take
advantage of the cache as much as you can.

What would the partitions on the first configuration gain you (over just a
single C:)? I thought the idea behind placing NTDS, etc on something
_besides_ C: was to get the performance benefits of extra spindles (as in
#2).

We have some budget money to replace domain controllers this year. Not
all of them but probably half of them. We've pretty much decided on 64
bit Dell PowerEdge servers. Most of the discussion is about disk
configuration. Two schools of thought exist here.
1) 2x73GB 15K drives in RAID1. Carve up the volume at the OS level with
20GB or so for the OS and the remainder for NTDS, Sysvol, and system
state backups
2) Two sets of 2x73 10K drives in RAID1. The first set is for the OS,
the second is for NTDS, Sysvol, and system state backups.
I've always liked physically separating the OS from the application
data. Others here like carving up the volume at the OS.
Any thoughts, opinions, suggestions?
tia, al
